Windows 7: SmartDefrag2: Half the screen filled with black cells

SmartDefrag2: Half the screen filled with black cells

I just defragged my two computers using IObit's Smart Defragger 2.6. One is a desktop and the other is a laptop. Although they are from different manufacturers, they have the same OS (Windows7 HP) and just about the same programs in use. The desktop is used more than the laptop.

On opening SD, the screen for the laptop didn't have many black cells; whereas the desktop showed about half the screen filled with continuous black cells and many black cells remaining within areas that were defragged/optimized.

I would appreciate knowing if the preponderance of black cells showing the desktop means anything?

That would depend on what the black cells indicate. If they represent free space on the hard drive (just as an example) it's possible the desktop has a larger hard drive than the laptop so it's showing more free space. But if the black cells mean something else...

A screenshot of the defrag screens including the legend of what the different colored cells mean would help. Also the size of both hard drives.

OK, here's a screen shot of SmartDefrag for my desktop. The Desktop's hard drive capacity is 640GB, and for the laptop it is 500GB.
Grey=Free space
Blue=Rarely used
Green=Frequently used
Purple=Directories
Orange=MFT
Black=Unmovable
Red=Fragmented
Blue=Moving

Since the black cells represent unmovable files, those would include System files (including hidden files), Backup files, System Restore files, Shadow Copy files, Zipped files, Compressed files, Encrypted files, Swap files (AKA Paging files), the Master File Table, to name just a few.

The more use a computer has, the greater the probability that more unmovable files will be created. But Windows 7 is a lot better at managing these files than previous OS versions. The greater concern would be if you're running out of hard drive space. As long as the hard drive isn't in the red I'd say everything is fine.

Thanks, Marsmimar. I was getting quite concerned as I had never seen so much black when doing a defrag. From the look of the screen, it looks as though about half my drive's capacity is taken up with a lot of stuff I don't know about. I would feel more comfortable if I could reduce the amount of black cells in order to free up room on the HD. Any suggestions on how to go about this?

Use Disk Cleanup. There's an option to delete unnecessary system files as well as deleting non-system files (steps 4 and 5.)

Disk Cleanup - Open and Use

You could also delete older system restore points and reduce the amount of hard drive space that's set aside for those restore points.

System Protection Restore Points - Delete

System Protection - Change Disk Space Usage

If hibernation is enabled and if you don't use it, you can disable it and gain back an amount of hard drive space equal to about 3/4 of your RAM.

Hibernate - Enable or Disable

I think these are the most common steps people take to regain hard drive space. This tutorial shows several more things you can do if so inclined. Not everything will apply to your computer so don't feel that you have to do everything.

Wow. Great advice. Will give it a try tomorrow and let you know how it turns out.

Well, I must say that my C drive is looking a lot, lot better after going through your suggestions. I should have approached this issue more scientifically to see just where those black cells were coming from. That is, I merely went step by step following your suggestions, and when finished, I took a look at the SmartDefrag's screen. What I should have done is taken a look at the SD screen after each adjustment. Anyway, as proof that the suggestions and effort were worth while, here's a pic of the C drive after all was said and done. BTW, if I were to guess at what procedure made the biggest difference (i.e., go rid of the most black cells), I'd say it was my re-setting how much should be set aside to record Restore Points. Somehow, the setting was at 50% and I reduced it to 5%.

What a difference between the before and after screenshots. Looks like you went from 44.3GB free space to 185GB. I agree that the biggest gain was changing how much space was set aside for restore points. That was a HUGE amount ... roughly 146GB.

Glad you were able to get back so much space. Thanks for posting back.
